In this HackerRank Java Static Initializer Block problem statement, we need to develop a program that accepts two lines of input. the first line of input is the breadth of the parallelogram and the second line of input is the height of the parallelogram. if both input values are greater than zero then we need to print the area of parallelogram otherwise print the java. lang.exception: breadth and height must be positive.


Java Static Initializer Block problem solution | Hackerrank


Problem solution in java7 programming.

static boolean flag = true; 
static int B,H;

static{

Scanner scan = new Scanner(System.in);
B = scan.nextInt();
scan.nextLine();
H = scan.nextInt();
scan.close();
if(B>0 && H>0){
    flag = true;

}else if(B<=0 || H<=0){
    flag=false;
    System.out.println("java.lang.Exception: Breadth and height must be positive");
}
}


Second code

static Scanner scan = new Scanner(System.in);
static int B = scan.nextInt();
static int H = scan.nextInt();
static boolean flag;
static {
    if(B<=0 || H <=0){
        flag = false;
        System.out.println("java.lang.Exception: Breadth and height must be positive");
    } else {
        flag = true;
    }
}
